An improvement direction for filter selection techniques using information theory measures and quadratic optimization (1208.3689v1)
Published 17 Aug 2012 in cs.LG, cs.IT, and math.IT
Abstract: Filter selection techniques are known for their simplicity and efficiency. However this kind of methods doesn't take into consideration the features inter-redundancy. Consequently the un-removed redundant features remain in the final classification model, giving lower generalization performance. In this paper we propose to use a mathematical optimization method that reduces inter-features redundancy and maximize relevance between each feature and the target variable.
